Matthew will be turning 4 in a few short weeks but he was in need of his bike sooner so we gave him his bike the other morning! He was soo excited and his little helmet is a Dieago helmet! He is doing pretty good on the bike now too. It is a bit tall for him but the smaller one is way too small. So once we learned how to pedal he gets around fine now. Though he has ou walk behind him as he did fall off the first morning. Thank goodness for training wheels and helmets!
